h Description: This is for your reference of the name of the Virtual Server
you will be using. You can type in your preferences.
h Internal Host IP Address: Internal Host IP Address refers to the
internal computer’s IP address that you want to use. This internal
computer’s IP address preferable to be manually set so you won’t have
to change every time you restart the computer.
h Protocol: Protocols are the protocol type that you want to set for your
internal host. For example, if you have a web server, you can set the
protocol as HTTP.
h External Port: This is referring to the port which broadcast by your
RNX-GX4. You can enter a range of the port for this setting. For
example, 80~90.
h Internal Port: This is referring to the specific service TCP/UDP port of
your internal host. For example, if you have a web server IP as
192.168.1.110, internal port 80, then you can set this virtual service like
the picture above.
IMPORTANT:
If you set your port as 8080, you will need to change the 8080 port in the “Remote Management
Port” under “Firewall” of “Security Management” to the other port. Otherwise, this may cause a
conflict between the Virtual Service and Remote Management.
3.7.2 DMZ
Some programs require having multiple port connection, such as Internet Gaming
programs, Video Conferencing programs, and Internet Phones. Due to the firewall
limitation, these programs will not be able to work under virtual service. The
purpose of a DMZ is to add an additional layer of security to your Local Area
Network (LAN); an external attacker only has access to equipment in the DMZ,
rather than the whole of the network.
